摘要

Resistance welding device comprises a welding transformer (8) having a primary side and a secondary side; two welding electrodes (23, 24) connected to the secondary side of the transformer and arranged on an adjusting arm; drives (3, 4) for moving the arm; a control unit arranged on the primary side between the transformer and a connection to a current network; and an electronic component of a rectifier switch and/or an inverted rectifier connected to the drive (3) for controlling and/or supplying the drive. Preferred Features: The whole rectifier switch is connected to the drive (3). The inverted rectifier is arranged between the rectifier switch and the transformer, and a drive rectifier is arranged between the rectifier switch and the drive (3).
